David Airlie Announces "Reverse Optimus" Multi-GPU

Phoronix: David Airlie Announces "Reverse Optimus" Multi-GPU

David Airlie has announced work on "Reverse Optimus", which is a new approach he's taking for poking laptops with multiple GPUs, namely the NVIDIA Optimus laptops with a discrete NVIDIA GPU and integrated Intel graphics...

Only if the big GPU can't go low enough in idle/2d modes. This is constantly improving, so in a generation or two only the most high-end mobile GPUs should require an integrated one too to keep power in check.

I couldn't find any recent numbers. It would be really interesting to see a comparison of the
power consumption of typical mobile IGPs and dedicated mobile GPUs running in 2d mode.
Even more interesting is the trend over the last say five years (for low- to high-end components).
